Per Welinder and Tony Hawk
Skateboarding pros turned entrepreneurial all-stars
In 1992, skate pros Per Welinder (left) and Tony Hawk (right) launched Birdhouse Projects, a company that manufactures skateboard components and apparel. Originally launched with other pro riders in mind, Birdhouse is now just one of many brands represented under Blitz Distribution, the parent company they created five years later to meet the needs of their diverse customer base.

Startup Woes
From meager beginnings to multimillion-dollar success
Like other pro riders of the time, Welinder witnessed the skateboarding industry grow from a small movement in the '70s to the multibillion dollar business it is today. When Birdhouse was launched in the early '90s, it was during a lull in the skateboarding industry. Welinder and Hawk couldn't get any outside financing, so the two were forced to use their own money from competition winnings to start the company.

Mat Hoffman
Revolutionizing the sport and the business
BMX pro Mat Hoffman is one of the most recognizable names in BMX riding. At just 16, he became the youngest pro rider the sport had ever seen. Hoffman is famous for his daring stunts, including base-jumping his bike off 3,500-ft Norwegian cliffs and setting the Guinness World Record for jumping his bike 50 feet above the ground. Frustrated by his bikes' inabilities to keep up with his limit-pushing stunts, he started creating his own line of bikes in 1991.

Izzy and Coco Tihanyi
Proving two heads are better than one
Twin sisters Izzy (left) and Coco Tihanyi (right) knew there was a lack of good surf instruction for women, so they decided to do something about it. Armed with only $320, the sisters started Surf Diva, a surf-school and surf-apparel company for women ages 18 to 25. The Tihanyi sisters will be celebrating a fruitful 10-year anniversary this year with the launch of a new swimwear line that will be debuting in major retail stores this spring.
